qcacld-3.0: unblock the state control param thread at end of SSR

Currently the state control param thread is unblocked 1st and then
the psoc transition is completed, there could be a chance that SSR
thread got scheduled out and wifi thread tried to comeup and issue
interface up which could fail because psoc transition is till in
progress.

So, unblock the wifi thread waiting on state control param after
stopping the psoc transition at the end of SSR.
